Figure 2From: The Arabidopsis LRR-RLK, PXC1, is a regulator of secondary wall formation correlated with the TDIF-PXY/TDR-WOX4 signaling pathwayValidation of the microarray data for differential gene expression by GUS staining of transgenic plants harboring pPXY::GUS, pPXC1::GUS , pPXC2::GUS and pPXC3::GUS. One-week-old plants for a-d, five-week-old plants for e-h and the floral stem was about 15 cm tall. (A) GUS staining in the cotyledons; (B) GUS staining in the shoot apex; (C) GUS staining in the hypocotyls; (D) GUS staining in the root tip; (E) GUS staining in the stem cross section; (F) GUS staining in the leaves.Back to article page
